Can't say I'm really a gadget man, more of a traditionalist but this little piece of kit which was bought as a Fathers day gift really works for me on a number of levels.
It does what it says on the tin and keeps the score for up to 4 players. It is easy to enter your score details and seems to be resistant to water so I have no problem leaving it attached to my bag. This also works well as I don't like to wear a watch on the course and this has the time in built so I can easily check it when it is clipped to the bag without having to delve into the pockets. I have not needed to change the battery as of yet either which is good.
As said for a traditionalist I like this little toy, works well for me so would recommend.
